A company has built a serverless application for its ecommerce website. The application includes a REST API in Amazon API Gateway that invokes an AWS Lambda function. The Lambda function processes data and stores the data in Amazon DynamoDB table. The Lambda function calls a third-party stock application API to process the order. After the ordered is processed, the Lambda function returns an HTTP 200 status code with no body to the client.
During peak usage when the API calls exceeds a certain threshold, the third-party stock application sometimes fails to process the data and responds with error messages. The company needs a solution that will not overwhelm the third-party stock application.
Which solution will meet these requirements?

  1. Configure the REST API in API Gateway to write the requests directly into DynamoDB. Configure a DynamoDB intrinsic function to perform the transformation. Set up a DynamoDB stream to call the third-party stock application API with each new row. Delete the Lambda function.
  2. Configure the REST API in API Gateway to write the requests directly into an Amazon Simple Queue Service (Amazon SQS) queue. Configure the Lambda function with a reserved concurrency equal to the third-party stock application's threshold. Set Lambda function to process the messages from the SQS queue.
  3. Configure the REST API in API Gateway to write the requests directly into an Amazon Simple Notification Service (Amazon SNS) topic. Configure the Lambda function with a provisioned concurrency equal to the third-party stock application's threshold. Set the Lambda function to process the messages from the SNS topic.
  4. Configure the REST API in API Gateway to write the requests directly into Amazon Athena. Configure the transformation of the data by using SQL with multiple query result locations set up to point to the DynamoDB table and the third-party stock fulfilment application API. Delete the Lambda function.

Answer(s): B



A developer is building an application that invokes AWS Lambda functions asynchronously to process events. The developer notices that a Lambda function fails to process some events at random times. The developer needs to investigate the failed events and capture the events that the Lambda function fails to process.
Which solution will meet these requirements?

  1. Add an Amazon EventBridge rule for the Lambda function. Configure the EventBridge rule to react to failed events and to store the events in an Amazon DynamoDB table.
  2. Configure the Lambda function with a dead-letter queue based in Amazon Kinesis. Update the Lambda function's execution role with the required permissions.
  3. Configure the Lambda function with an Amazon Simple Queue Service (Amazon SQS) dead-letter queue. Update the Lambda function's execution role with the required permissions.
  4. Configure the Lambda function with an Amazon Simple Queue Service (Amazon SQS) FIFO dead-letter queue. Update the Lambda function's execution role with the required permissions.

Answer(s): C



A company is adopting serverless computing for some of its new services. A development team needs to create a serverless infrastructure by using AWS Serverless Application Model (AWS SAM). All infrastructure must be deployed by using AWS CloudFormation templates.
What should the development team do to meet these requirements?

  1. Add a Resources section to the CloudFormation templates that contains AWS::Lambda::Function resources.
  2. Add a Mappings section to the CloudFormation templates that contains AWS::Serverless::Function and AWS::Serverless::API.
  3. Add a Transform section to the CloudFormation templates. Use the AWS SAM syntax to define the resources.
  4. Add a Parameters section to the CloudFormation templates that specifies the relevant AWS SAM Globals section.

Answer(s): C



A company needs to deploy all its cloud resources by using AWS CloudFormation templates. A developer must create an Amazon Simple Notification Service (Amazon SNS) automatic notification to help enforce this rule. The developer creates an SNS topic and subscribes the email address of the company's security team to the SNS topic.
The security team must receive a notification immediately if an IAM role is created without the use of CloudFormation.
Which solution will meet this requirement?

  1. Create an AWS Lambda function to filter events from CloudTrail if a role was created without CloudFormation. Configure the Lambda function to publish to the SNS topic. Create an Amazon EventBridge schedule to invoke the Lambda function every 15 minutes.
  2. Create an AWS Fargate task in Amazon Elastic Container Service (Amazon ECS) to filter events from CloudTrail if a role was created without CloudFormation. Configure the Fargate task to publish to the SNS topic. Create an Amazon EventBridge schedule to run the Fargate task every 15 minutes.
  3. Launch an Amazon EC2 instance that includes a script to filter events from CloudTrail if a role was created without CloudFormation. Configure the script to publish to the SNS topic. Create a cron job to run the script on tile EC2 instance every 15 minutes.
  4. Create an Amazon EventBridge rule to filter events from CloudTrail if a role was created without CloudFormation. Specify the SNS topic as the target of the EventBridge rule.

Answer(s): D



A developer needs to deploy an application in three AWS Regions by using AWS CloudFormation. Each Region will use an AWS Elastic Beanstalk environment with an Application Load Balancer (ALB). The developer wants to use AWS Certificate Manager (ACM) to deploy SSL certificates to each ALB.
Which solution will meet these requirements?

  1. Create a certificate in ACM in any one of the Regions. Import the certificate into the ALB that is in each Region.
  2. Create a global certificate in ACM. Update the CloudFormation template to deploy the global certificate to each AL
  3. Create a certificate in ACM in each Region. Import the certificate into the ALB for each Region.
  4. Create a certificate in ACM in the us-east-1 Region. Update the CloudFormation template to deploy the certificate to each ALB.

Answer(s): C
